In full nervousness for the cutting of submarine cables, China has a final weapon: a radio in steroids

by

The Submarine cables They are one of the most important elements today. Not only is it a huge infrastructure that organizations and companies continue to develop -with such ambitious projects as the Meta cablewhich will take more than one return to the earth-but have become today thanks to the Ukraine War already maneuvers at the South China Sea. It is in this conflict that Some cut cables They have triggered the fear of running out of the Internet, and everything that implies. These cables are protected, but can be damaged by ships. Now, China has presented a device designed with a task in mind: cut underwater cables. And it is the first time that someone announces that he has a tool capable of interrupting critical underwater networks. The importance of cables. There are more than 1.4 billion meters of submarine cables that connect all countries. There are other thousands of kilometers planned, and the vast majority of communications in some countries depend on these cables. 95% of them in the case of Australiafor example, and I know esteem that 95% of the data managed by the American population and 75% by China depend on them. They are vital for the Internet and all that this implies, such as streaming, artificial intelligence or servers, and this year they have become protagonists in war scenarios. Countries in conflict have realized that they can cause great damage by cutting these cables by boats or through more sophisticated techniques, such as Sound attacks. There are times that They are simple accidentsbut the suspicion that a damaged underwater cable corresponds to an enemy attack is something that is there. And more now with what they just announced from China. The Chinese device. As we read in South China Morning Postthe State Key Laboratory of Deep Water Crewing Vehicles and the Scientific Research Center of Ships of China, have developed a tool that describe as “compact” and that is capable of cutting the most sophisticated underwater communication lines or energy in the world. As it is a tool designed specifically for this, it has been conceived to cut cables at depths of up to 4,000 meters. There are no cables right now that they are in such depth, but its creators have provided the device with a completely sealed titanium alloy housing to resist that enormous pressure. This is Haidu, and can carry this “radial” Your weapons. The device is equipped with a kilowatt engine and as a cutting tool uses a 150 millimeter diamond wheel that rotates at 1,600 revolutions per minute. Let’s say it is the mixture between a protected drone to endure very high pressures and a radial. This cutting tool allows to destroy up to armored cables that have steel layers, rubber and polymeric coating. And its form has been designed so that it can be integrated both in manned and non -manned submersibles of China. For example, haidou vehicles or Fondouzhe could have this as one of their tools. He Haiduas a curiosity, it is an unmanned submersible in the form of fish and eyes drawings and fins created for exploration. He Fendouzhe It is a manned submarine, also for research and exploration. World Order. As we say, threaten to cut underwater cables It is not something new. We have seen it in the Ukraine War, but it is the first time that a country officially reveals a tool designed exclusively for that task. Of course, those responsible affirm that the tool has been created for civil purposes. Which is it? Rescue and mining operations in the maritime bed, but it is evident that it is a tool that is surely causing the other neck itching in rulers around the world. It is clear that such a tool can destabilize communications in a crisis and be used strategically during an attack. And it is not only communication, but everything that has to do with the Internet, such as servers and services that depend on them. Debate and consequences. When a cable is cut, communications are rapidly redirected through another, since they are prepared to have a large bandwidth. Therefore, important interruptions are not usually produced, but that cable You have to repair itbeing a fairly expensive process. Now, when it is not a single cut cable, but several, that connection may be set. It is what has led to a debate about the need to protect infrastructure. NATO has launched The mission “Baltic Sentry” To patrol sensitive regions with airplanes, drones and warships. There are also companies that are offering advanced cable monitoring services, answering all measures to a single issue: the protection of infrastructure and early detection to prevent cuts. That there are countries that have already made public that have sophisticated tools for cutting submarine cables and interfering with world geopolitics, is a new headache.

The EU has a weapon in the war of tariffs with the US and is to direct them to Republican states

by

The EU will respond to The tariffs of the US with the same currency. Or rather, with the same policy, applying a curious law of the talion that from Brussels summary of form Simple but resounding: “Euro per euro, dollar per dollar.” After seeing how Donald Trump pressed on Wednesday the tariff red button, activating 25% rates To imports of European aluminum and steel, the European Commission has decided to replicate by applying taxes worth 26,000 million euros to a long list of American goods. The figure (26,000) is overwhelming, but the most interesting thing is what it hides. The EU has decided “hit where it hurts” to Trump, penalizing products that in many cases leave Great Folders of Republican votes. The goal is evident: press Trump from outside … and from within. A word: tariffs. To Trump He likes tariffs. He has openly recognized it, even as a White House candidate, when assured That ‘Tariff’ is, in his opinion, “the most beautiful word in the dictionary.” In the 50 scarce days He has sitting in the Oval Office has repeated that word a few times, many. Sometimes for disdain in addition. Others, Like this weekto announce a turn in the US policy towards certain foreign goods. On Wednesday the Republican Impulse 25% tariffs to all steel and aluminum imported to the US, a measure that connects with similar ones of his first mandate and that he has not laid anything well in Canada or the EU, who have already decided to play their own letters to respond. In the case of the EU, the European Commission announced yesterday “countermeasures” that will basically translate in applying tariffs worth 26,000 million of euros to certain US exports. What does Brussels plan? Use the stick and carrot. Yesterday the president of the CE, Úrsula von der Leyen, insisted In the importance of commercial relations between the EU and USA, the “harmful” effect of the encumbrances and their hand lying to Washington, but with them he announced EU’s plans to replicate Trump with tariff 26,000 million of euros. Moreover, he has already decided how he will: the EU will advise the coup throughout April, in two phases. On April 1 he will reactivate the “countermeasures” that he had already activated between 2018 and 2020, after Trump’s first government had Increased your rates also unilaterally. That punishment package that Brussels wants to recover It was suspended After the arrival of Joe Biden to the White House and, according to the EU calculationswill now serve to respond to economic damage worth 8,000 million euros caused by US tariffs. The second Brussels movement will reach mid -April (to be precise on the 13th) and will seek to counteract the damage worth another 18,000 million euros that, again According to EU calculationswill have the new Trump tariffs in European exports. Between one and the others they will add 26,000 million. That this last “countermelted” later has an explanation: it is new and before Brussels wants to have it well tied with the 27 EU countries. That’s all? No. von der Leyen argues That the EU wanted to be equitable in its replica: “Since the US applies tariffs worth $ 28,000 million, we respond with countermeasures worth 26,000 million euros,” he alleges. However, there is something so or even more important than those figures: what are applied to. The EC has decided to refine the shot and direct its punishment to certain US goods that can be sensitive to Trump for a very simple reason: they leave states that They support it at the polls, to him and the Republican party. “Hit where it hurts”. A senior EU official summarized it clearly (and forcefully) yesterday in statements a The Guardian: “We try to hit where it hurts.” In the American merchandise list that has the CE in the spotlight, which can be Consult onlinethere are motorcycles, whiskey, wine, honey, meat, cheese … a long payroll of products in which Some experts They have already seen some intentionality. For example, it affects iconic products, with a symbolic value, such as Harley-Davidon motorcycles or The Bourbona wiski with an important roots in the US. The importance of soybeans. The same source that spoke with The Guardian I quoted Another clear example: soybeans, interesting for several reasons. The first is its commercial weight. At least in 2019 it was The main supplier of soy of Europe, far ahead of Brazil, the second supplier. The specialized magazine PROGRESIVE FARMERbased in Alabama, points that Europe buys about 6.5 million metric tons of soybean exports and soy flour with a value of around 3,000 million dollars. Despite this bond the same source of Brussels assured The Guardian that for the EU would not mean any trauma to look for the supply in another market. “We love soybeans, but we are gladly bought from Brazil, Argentina or any other lujar,” reason. A year ago the EU has already raised sensitively The amount of Brazilian soy. The third factor that makes soybeans a sensitive merchandise for Trump, in addition to its weight in the commercial flow with Europe and the possibility of buying it in other countries is where it occurs in the US. Looking at the Republican Party. Soybean is one of the goods more relevant in agricultural exports to the EU. And a state relevant In the cultivation of American soybeans it is Louisiana, a territory especially sensitive For Donald Trump’s game. From there is the Republican Mike Johnsonthe president of the House of Representatives. Luisiana is also one of the states that was dyed red (Republican color) during the presidential elections of 2024, just like Iowa, Indiana, Missuri, Ohio or the two Dakotas. Everyone has more than having facilitated Trump’s access to the White House: they also stand out in The soy map United States. “Smart” tariffs. Something similar happens with the bourbon, especially linked to Tennessee and Kentucky, Traditional Folders Republican vote. The nickname Bluegrass State has also choosing from mid … Read more

Xiaomi’s weapon to compete with the best in AI for mobile

by

Within the framework of the Mobile World Congress 2025, Xiaomi has announced great plans for 2025. Xiaomi 15 Ultra is one of them and, together with Xiaomi 15make up the new high range for this year. These two phones arrive with Hyperai, the interpretation of the Chinese manufacturer. Xiaomi has come something after his rivals to integrate multiple functions of AI so natively, but says the saying that better. I have been able to try some of these first -hand functions, so I’m going to tell you what Xiaomi has implemented on these phones, and what to expect from this first stage. This is how Xiaomi money earns – they attract you and catch you The novelties of Hyperai Hyperai’s novelties are divided into seven blocks. In all of them there is a common point: it is a native integration. In other words, they are deep integrations at the system level and it has been sought that the experience be as far as possible to use a third -party service. That said, this is what you should know about Hyperai in Europe. Gemini: Integration with Gemini is completely native. It works as a system assistant, it is invoked with the ignition button and, the most mold, you can read the content of all our apps if we give permission. This allows you to make summaries, translations, and others. Writing with AI: We can change the style of the message, make summaries, review texts, etc. Gallery editor with AI: We can improve the clarity of the photos with AI, make generative expansion of them (such as the adobe tool), delete objects, or create videos with AI. Voice recognition: Transcripts, distinction between speakers, summaries, translations and custom labels for each speaker. Interpret conversations with AI: Face to face interpretation, automatic language recognition, translation templates. CALL INTERPRETE Subtitles with real time Xiaomi’s AI is quite similar to view on the rest of the phones that use the Nano Gemini model: translations, text improvements, editions in the gallery … Those that require Internet connection, such as the expansion of images, also require Xiaomi account. The deletion of people is improvable. Generative for edges. After trying some of these functions, I am clear that Xiaomi’s AI is in its first steps. In this example, quite easy by the way, I wanted to eliminate the person from photography. The result is somewhat inconsistent. In the second example I wanted to fill in space in photography. If we expand, we see that elements such as the fork contain errors. Writing functions are available in apps such as WhatsApp. Some others are native, such as interview transcription in their recorder app. Regarding text corrections, they work quite well. It is a useful function for professional emails and work environment. Transcripts work relatively well (with some errors, of course), but the phone takes a long time to process the results. I would like this processed to be done in the background to expedite the process. Xiaomi has reached AI a tuño late, but the integration promises. Not taking some year of experience makes it end up noticing a certain distance in front of some of its competitors, so the following updates have an important work ahead: reach the level of the best in the market.

A startup claims to have the weapon to end China’s monopoly on rare earths: hard drives

by

In the technological era and Energy transition to renewables and the electric car In which we are, the Rare earth They have become the most valuable currency. This set of elements has become essential for many industries, but there is a problem: China dominates both mining and, above all, Rare Earth Metals Productionand he does not hesitate to use them as a throwing weapon in the Technological and Commercial War in which we are. While west Decide which are the next steps In the search for the gold of the 21st century, there are already those who work to obtain rare earth elements from wherever it is thanks to recycling. And that hard drive that has been in the drawer for years is a treasure. ‘Chrysistunity’. “Rare earth” is the name with which we call a group of 17 minerals that are used to manufacture components of electric car batteries, precision medical instruments, speakers or elements of wind turbines, among many other applications in virtually all sectors. Taking them out of the earth is not as much problem as their refining, since it is a process that does not get along with Western pollution restrictions. That is why we were delegating this task to China and, now, the Asian giant dominates practically 90% of production. So important are that the country usually uses the export of rare earth metals when it receives a new western commercial blow and even in the Ukraine War we have seen Trump condition US support to the supply of rare earth. But before each crisis, there is an opportunity. Old hard drives. In the absence of being able to produce them, why not get those elements through recycling? With the plastic we do not do it very well, but with other elements, and in the case of rare earths, it is something that can work. That is precisely what the company has proposed Hypromaga startup founded by personnel from the Metallurgy and Materials School of the University of Birmingham that, as we read in Financial Timeshas focused on the recycling of hard drives. These components once dominated our PCs and, although they remain of great value as external discs and, above all, as components for NAS systems, they have gradually been separated by much faster SSDs and that have been lowering price. And these hard drives have some components that are manufactured thanks to rare earth elements, such as magnets that allow their operation. Recycling. Gavin MUDD is the director of the Critical Mineral Intelligence Center of the United Kingdom and comments that the country imports between 5,000 and 10,000 tons of rare earth magnets every year in the form of finished products and components, but only 1% of that figure Recycle. He affirms that it is not an isolated case and that it is an amount similar to that of other industrialized nations. “We need to consider future domestic production, and that leads us to consider recycling,” he says. And that is where Hypromag technology comes into play. They claim that their technique allows them to extract the magnets that contain rare earths, which weigh between 10% and 15% of the hard disk itself, and obtain the elements sought. To do this, they have a great drum that they fill with even a ton of waste at the same time and, after closing the hermetic doors, introduce pure hydrogen inside. Then, hydrogen unstals enter the fissures of the magnets, causing them to break and separate them from the surrounding material. After this process, which lasts between four and eight hours, a powder composed mainly of the ingredients of the magnet – the neodymium – falls to the bottom of the container, while other elements such as steel, nickel and aluminum are separated and also can also be recycle. Subsequently, they grind the sifted material and an alloy occurs that can become a magnet again. Different approaches. There is another company that is in garlic and that has also spoken with Financial Times with a tone of competition that, in the end, is the one that can advance the industry of rare earth recycling. This company is called Material Cyclic And he affirms that his method is better than that of “magnet to magnet” because he allowed to crumble each component of the elements instead of separating magnets, on the one hand, iron and steel on the other. Ahmad Ghahreman is the executive director of this company and affirms that its approach allows companies to use the rare lands as they want, not only as magnets. And he compared the two approaches with the recycling metaphor of a pizza: “When recycles pizza with our technology, raisins from flour pizza, salt, pepper and all other ingredients. With the other, pass from pizza to the dough. ” An ambitious patch. Despite competitiveness in his words, Ghahreman considers that both methods are valid and “profitable.” In 2024 they produced 100 tons of rare earth oxides, but they hope to reach 600 tons for the end of this year. In addition, they have plans to open another plant in the United States with a capacity of 1,200 tons per year and have plans to open facilities in Canada and Europe in 2028. Hypromag, on the other hand, hopes to produce between 25 and 30 tons per year in its first phase, but with extension plans to 350 tons thanks to a new plant in Germany and another 1,000 tons of annual alloys with a projected plant in Texas. They are less concrete plans, but the objective of both companies is the same. Clue. Allan Walton, the founder of Hypromag, comments that this technology “is a way of extracting large amounts of rare earths and creating a domestic supply,” and the truth is that the recycling of rare earths is something that has been speaking for years, but It was always a challenge. And it is something that is being sought in various parts of the world. For example, … Read more

Student dies after being shot by classmate at Nashville high school

by

NASHVILLE, Tennessee, USA — A student was killed and another wounded Wednesday when they were shot in the cafeteria of a Nashville high school, nearly two years after a school shooting in the city that sparked an emotional debate over gun control in Tennessee. The attacker, a 17-year-old boy who was also a student at Antioch High School, later committed suicide, Metropolitan Nashville Police spokesman Don Aaron said during a news conference. Police identified him as Solomon Henderson. Police Chief John Drake said the gunman “confronted” a 16-year-old student in the cafeteria and began shooting, causing her death. Police identified the student as Josselin Corea Escalante. Drake mentioned that police are investigating a motive and whether the shooter was specifically targeting the students he shot. The student who was injured suffered a graze and was treated and released from the hospital, Drake reported. Another student was taken to a hospital to treat a facial injury that occurred during a fall, Aaron said. There were two school resource officers in the building when the shooting occurred around 11 a.m. crazy time, Aaron said. They were not in the vicinity of the cafeteria and by the time they got there, the incident was over and the attacker had already committed suicide, Aaron added. The school has approximately 2,000 students and is located in Antioch, a Nashville neighborhood about 10 miles (16 kilometers) southeast of downtown. At a family safety center near a hospital, officials helped shocked parents reunite with their children. Dajuan Bernard was waiting at a Mapco gas station to meet his son, a 10th grader, who was held in the auditorium with other students that Wednesday afternoon. He learned about the shooting from his son, who “was a little scared,” Bernard said. Her son was upstairs from where the shooting occurred, but told her he heard the shots. “He was fine and he let me know that everything was fine,” Bernard said. “This world is so crazy, it could happen anywhere. We just have to protect the children and educate them well to prevent them from even doing this. “That is the hardest part,” he commented. Fonda Abner, whose granddaughter is a student at the school, said Antioch High School does not have metal detectors that would alert school authorities to the presence of a weapon. She said her granddaughter had called her a couple of times, but she only heard commotion and thought it was an accidental call. They spoke briefly until the call was disconnected. “It’s nerve-wracking waiting out here,” Abner said. United Family Fellowship, a church located in Antioch, hosted a vigil Wednesday night “for anyone in the community who needs a space to pray, process and find comfort,” the church posted on its Facebook account. Hours earlier, Adrienne Battle, superintendent of Nashville schools, said public schools have implemented a “range of security measures,” including partnerships with police for school resource officers, security cameras with weapons detection software, installing shatter-resistant film for security windows and vestibules that are a barrier between outside visitors and the main entrance. “Unfortunately, these measures were not enough to stop this tragedy,” Battle said. He added that there are questions about whether stationary metal detectors should be considered. “Although previous research has shown them to have limitations and unintended consequences, we will continue to explore emerging technologies and strategies to strengthen school safety,” Battle said. In October, a 16-year-old Antioch High School student was arrested after school resource officers and school employees discovered through social media that he had brought a gun to school the day before. When he was detained the next morning, officers found a loaded gun in his pants, police said. Wednesday’s school shooting came nearly two years after a gunman began shooting at a separate private Nashville elementary school, killing six people, including three children. The tragedy sparked a months-long effort among hundreds of community organizers, families, protesters and many more pleading with lawmakers to consider passing gun control measures in response to the shooting. However, in a state dominated by Republicans, GOP lawmakers refused to do so. With the overwhelming Republican majority intact after the November elections, it is unlikely that lawmakers’ stance has changed enough to consider any significant bill addressing gun control. Instead, lawmakers have been more open to adding more security to schools, including passing a bill last year that would allow some teachers and staff to carry concealed firearms on public school grounds, and ban parents and other teachers to know who was armed. Antioch, a growing and diverse area of ​​Nashville, has seen other shootings in recent years. A deadly 2017 shooting at Burnette Chapel Church of Christ killed one woman and injured seven people. And in 2018, an attacker killed four people at a Waffle House restaurant. State Rep. Shaundelle Brooks ran for office largely because of the death of her son in the Waffle House shooting and was elected last year after the Covenant shooting. She said the Antioch High School shooting reinforces the need for gun control reforms. “We must improve,” he asserted. “Since losing my son, Akilah, in a mass shooting in 2018, I have been fighting to ensure this never happens again,” the Nashville Democrat said in a statement. “Here we are almost 7 years later, and our communities are still affected by gun violence.” Samantha Dickerson had taken her 14-year-old son’s phone away as punishment, so when she received a message from his school about the shooting, she had no way to contact him. “I was nervous,” she said. “I was really about to collapse.” After about three hours of waiting, she finally received a call from her English teacher and spoke to her son. “When I heard his voice, I just started crying,” she said. ___ Associated Press writers Kimberlee Kruesi in Nashville and Adrian Sainz in Memphis, Tennessee, contributed to this report. ___ This story was translated from English by an AP editor with the help of a generative artificial intelligence tool.
